Thefoheifule referredxo in there Letters Patent and making'part ofthesume `is a full, clear, and exact description thereof, "reference' beinghad to the accompanying,drawings and to the letter-sof reference markedthereon makingr a part of this specification.

The nature of my invention consistsin the con- `struction andarrangement of a'. device for spreading hay, as will be'rnore fullyhereinafter set forth.

Ivn order to enable others skilled i'n'the art to which our inventionapporta-ins to make and use the same,

we will now'proceed to describeits construction and operatiom referringto' the annered drawings, in

.Figure 1. is a sideelevation of our machine, one

Figure 2 is a longitudinal-vertical 'section of the sleeve, with thefork-arm 'passing through the same;

Figure 3 is a side view of the draft-pole support;

f Y' Figure 4 is a horizontal section of the 'mechanism for startingandstopping the motion .of the`ciauks,.

arms, end forks; and 4 "Figure 5 is a front view of one' of the fforks.

vA represents the axleof ou.r maohine, having aseries of 'bent orangular beams, B B, attachedpby .means of loops or;boxes'a a secured'ontheir umleisi'des atthe angle through which the axlepasses.

The beamsB B are, at their front ends, connected by a cross-bar, O, andat their rear ends are standards I) D, connected b v'atop cross-,bar E,and braced by .liraces G G, the whole forming a frame which oscillatesor rocks upon the ax'le A.

Upon the rear sides of the standards D D, in suit-'- 'ahlejournal-boxes, are placed two crank-shafts H-H Ione above theother,.having any desired number and forms of cranks, but soarrangedthat the correspondngcx-anks ot' eachshaft'donot run parallel, and notwo cranks on -the same shaft' run in' the same direcu n'.- fUpon eachclank ofthe .upper shaft ispivotcd the upper end of au arm; I, whichlaissestluohgh asleevc b b, againstv which the arm I bears.-

vA't thelower end of the arm I', ou each side, is

4placed a pin, d, around which theiwire tine e is wrapped,l

of speed of 'the forks when-it acts upon the hay, making a much moreeii'ective machine.

The sleeve J can he'placed-on the upper shaft'and the arm 'pivoted onAthe lower shaft, instead oi' eine cursa, as above mentioned.

Motion is communcatedt-o the cmnkshafts, arms, and forks by means of acog-wheel, l, attached to theinsideof one ofthe wheels ot' the machine.

mounted loosely upon an auxiliary shaft, M, which has its bearings upontwo of. the beams B B..

-A--'lhis latter cog-wheel L gears with? a cog-wheel, N, secured to oneof the crank-shafts H,; and this in turn .with asimilar cog-wheel uponthe 'other crank-shaft. r'llhus the two crank-shafts are made to revolvein opposite directions.

The intermediate cog-wheel L is moved sideways away from the wheels Kand N by means of a lever,

O, pivoted upon one of '.the beamsB, 'for the pui'pose of .stopping themotion loi the forks whenever desired,V and to stai-t them again atwill. Y Upon the axle A is placed a standard, QP, the lower end ofwhiclris provided with a loop or eye through which'the axle passes, andis secured by a key or other suitable device.l

At the upper endof the standard I the draft-pole R is secured, the rearend of said draft-pole being'r provided with the driveis seat. i, Insuitable journal-boxes across the draft-pole 'Bris a shaft, provided atone end with a cog-wheel and pulley, VS, as well as a lever, T, forturning the same 'at will.

Around said pulley is a chain, h, one .end of which is secured to theiront. cross-bar O, and the other to can from his seat raise and lowerthe frame and forks same in any position that it may be placed.

' 'The front end of the pawl h is 'pivoted to a foot"- lever, n, pivotedto the side of the draft-pole R,"in 'such a position that the driver canreacbjt with his foot, and, by pressing on the foot-leven withdraw the"pawl from the wheel'S, allowing it to be turned nby the use of the leverT.

Thns,at the will of' the operator, the forks may be elevated ordepressed while the machine is in motion, 'at the same -time notLinterfering withy the-'faction of the forks, which makes the machineveiy effectual on uneven' ground as well as on even ground.

Having thus fully described our invention,

than one crank, as generally used, and this increase- This eog-wheelgears with, another cog-wheel, L,

the rear end of one of the beams B, so that the driver crank-shalt, andthe two shafts revolving a-t ythe same time in opposite directions,substantially as andv for the purposes heroin set forth. i

2. The oscillating or rocking frame B 0 D E G, constructed as described,in combination with the crank-shafts H H, gearing for revolving thesm'e,

arms I I, sleeves J J, chain h, wheel S, lever T, and pawl or dog my,all arranged and operating substantally as and forthe' purposes hereinset forth.

In' testimony that we claim the foregoing, we have hereunto set ourhands this 3d day of January, 1870. I, THOMAS J. CLARK.
